The wonderful and most interesting world of heating and air conditioning has always been changing year by year.
If you trace it back to the very beginning of time, heating and air conditioning was always on the rise.
Even when there was nothing but dry ice in a tub for a form of the most earliest air conditioning, all the way to the invention of the first hot water boiler which created the send form of heating. Of course the very first form of heating goes all the way back to the caveman days with fire. Which in turn could actually be an early fireplace. Then as we move on through time the creation of the very first furnace, the window air conditioning system unit and then of course, the major breakthrough in all heating and cooling technology history. Which that was the invention of the central heating and air conditioning system unit. Today, mostly every home in the country is heat and cooled by the power of central heating and air conditioning systems. It could be commercial heating and air conditioning systems for big buildings and businesses, and then residential heating and air conditioning systems for people’s homes. If you really trace back the roots of HVAC all together, you will find that it has been quite an amazing journey all together and that there is a lot more to come as the future moves on forward. Heating and air conditioning technology is always changing and it never will stop changing I am pretty sure.
